T430s - Won't Start

‎09-19-201610:41 PM

Hello,

I have replaced screen on my T430s (used from T420s, because they are similar), before fully assembling (all the bottom screws), I tried to boot on battery and everything worked fine. After I finished assembling it, I couldn’t start my computer on battery, only with AC adapter. Battery is genuine (Panasonic came with T430s), I can charge or discharge it, tried battery gauge reset, tried to reset bios (take out CMOS battery), updated BIOS, nothing helps, by the way works with my T420s just fine (tried T420s battery on T430s same, nothing). Removing AC adapter causes laptop to shut off immediately.

It is hard to be sure without seeing it, but I think it is most likely the main (7-amp??) fuse by the battery connector, which is similar to the fuse for AC input. The main battery fuse is separate from the smaller charging fuse.
